Steps to Remove Water from iPhone Speaker:
Download the Shortcuts app (it should already be on your iPhone)
Download the Water Eject shortcut
Open the Shortcuts app
Tap the Water Eject shortcut
Press "Begin" to start the water removal process
Important Tips:
Do not wear headphones during this process14
Turn the volume all the way up for maximum effectiveness4
The shortcut uses a low-frequency tone to vibrate water out of the speakers12
Additional Recommendations:
After using the shortcut, wipe your device with a soft, lint-free cloth1
Gently tap the charging port against your palm to remove trapped water1
Place the iPhone in a dry area with airflow to help dry out any remaining moisture1
Caution:
Do not run the shortcut for an extended period, as it could potentially damage your speakers1
If water issues persist, give your iPhone time to dry out completely4
Time is often the best solution, and your speakers should return to normal within 24 hours3. https://lubiehrubie.pl/wiadomosci/iphone-i-usuwanie-wody-jak-poradzic-sobie-z-problemem-i-uratowac-swoje-urzadzenie/  https://siit.co/blog/how-to-get-water-out-of-your-phone-quick-and-easy-guide/15769
